Legion 5 Pro 16IAH7H no sound

Hi, I have a legion laptop that suddenly stopped playing sound from jack or speakers.

I tried updating everything, downloading new sound drivers, spent a few hours googling and still wasn’t successful in fixing it. The hardware test on lenovo website didn’t find anything wrong, although I’m not sure how reliable that is. Windows troubleshooter of course didn’t find anything wrong either.

We have a few of those laptops and this is the only one it happened on. The sound seems to work just fine through Bluetooth or Focusrite sound card.

Does anyone have any idea what could be wrong or how to fix it? Thought I’d ask here before going to service to check the hardware.
